Understanding Fractions: Comparison Techniques

This video tutorial explains how to compare fractions using different methods. It begins with comparing fractions with the same denominators by looking at numerators. It then covers comparing fractions with the same numerators by understanding the inverse relationship between numerators and denominators. The tutorial introduces the cross multiplication technique and converting fractions to decimals for comparison. Finally, it discusses methods for comparing three or more fractions by finding a common denominator or converting to decimals.
